sending all the syslog messages to the new IP address, provided the access point can reach the syslog
server IP address.
You can configure the syslog server for access points and view the access point join information only from
the controller CLI.
Note
Important Information for Controller-Based Deployments
Keep these guidelines in mind when you use the C9136I Series AP:
• The AP can only communicate with Cisco wireless controllers.
• The AP does not support Wireless Domain Services (WDS) and cannot communicate with WDS devices.
However, the controller provides functionality equivalent to WDS when the AP joins it.
• CAPWAP does not support Layer 2. The AP must get an IP address and discover the controller using
Layer 3, DHCP, DNS, or IP subnet broadcast.
• The AP console port is enabled for monitoring and debug purposes.
• All the configuration commands are disabled when the AP is connected to a controller.
Configuring DHCP Option 43
You can use DHCP Option 43 to provide a list of controller IP addresses to the access points, enabling them
to find and join a controller.
The following is a DHCP Option 43 configuration example on a Windows 2003 Enterprise DHCP server for
use with Cisco Catalyst lightweight access points. For other DHCP server implementations, see the product
documentation for configuring DHCP Option 43. In Option 43, you should use the IP address of the controller
management interface.
DHCP Option 43 is limited to one access point type per DHCP pool. You must configure a separate DHCP
pool for each access point type.
Note
The C9136I AP uses the type-length-value (TLV) format for DHCP Option 43. DHCP servers must be
programmed to return the option based on the access point DHCP Vendor Class Identifier (VCI) string (DHCP
Option 43). The VCI string for the C9136I Series access point is:
Cisco AP C9136I
The format of the TLV block is as follows:
• Type: 0xf1 (decimal 241)
• Length: Number of controller IP addresses x 4
• Value: IP addresses of the wireless controller management interfaces listed sequentially in Hex code.
